Description

Foreliggende oppfinnelse vedrører en trykkakkumulator for å etablere nødvendig kraft til å betjene og operere eksternt undervannsutstyr, så som hydrauliske og/eller mekaniske systemer, omfattende et hovedlegeme med et indre langsgående hovedkammer som er oppdelt i minste tre delkamre som er adskilt fra hverandre ved hjelp av innbyrdes, mellomliggende stempler, hvor et første av nevnte kamre er et kompenseringskammer, innrettet til å innta samme trykk som omgivelsene, og et tredje av nevnte kamre er et trykkammer. Oppfinnelsen vedrører også anvendelse av en trykkakkumulator. The present invention relates to a pressure accumulator to establish the necessary power to operate and operate external underwater equipment, such as hydraulic and/or mechanical systems, comprising a main body with an inner longitudinal main chamber which is divided into at least three sub-chambers which are separated from each other by means of mutually intermediate pistons, where a first of said chambers is a compensating chamber, arranged to assume the same pressure as the surroundings, and a third of said chambers is a pressure chamber. The invention also relates to the use of a pressure accumulator.

Oppfinnelsen har befatning med systemer og metoder som normalt sett benytter seg av en akkumulatorfunksjon for å skaffe nødvendig energi for å kunne betjene mekaniske eller hydrauliske systemer eller utstyr, og kan benyttes for systemer som har behov for akkumulert kraft for å kunne operere, uavhengig av om utstyret er plassert på havbunn, plattform, fartøy, innretning eller på land. Med uttrykket akkumulator, må det forståes et system som har en egenskap som muliggjør magasinering av energi ved hjelp av å pumpe gass eller væske inn i en kammer eller beholder som på forhånd, eller i ettertid, er/blir utsatt for et mottrykk ved hjelp av komprimert gass, luft eller en fjærfunksjon. En slik akkumulatorfunksjon nevnes heretter under benevnelsen akkumulator. The invention is concerned with systems and methods that normally use an accumulator function to obtain the necessary energy to be able to operate mechanical or hydraulic systems or equipment, and can be used for systems that need accumulated power to be able to operate, regardless of whether the equipment is located on the seabed, platform, vessel, facility or on land. The term accumulator must be understood as a system that has a property that enables the storage of energy by pumping gas or liquid into a chamber or container which is/is exposed to a back pressure beforehand, or afterwards, by means of compressed gas, air or a spring function. Such an accumulator function is hereinafter referred to as accumulator.

Oppfinnelsen vil på en forenklet måte representere en akkumulatorfunksjon som kan initieres ved behov. Oppfinnelsen gjelder både systemer som benytter akkumulatorfunksjonen direkte på legemet som skal aktiveres, så vel som systemer som nytter akkumulatorfunksjonen indirekte via hydrauliske eller pneuma-tiske systemer. In a simplified way, the invention will represent an accumulator function that can be initiated when needed. The invention applies to both systems that use the accumulator function directly on the body to be activated, as well as systems that use the accumulator function indirectly via hydraulic or pneumatic systems.

Oppfinnelsen vil være spesielt egnet til systemer, med behov for akkumulatorfunksjon, som normalt forlades ved et omgivelsestrykk for deretter å flyttes til et annet omgivelsestrykk. Typiske områder er midlertidig utstyr til bruk på havbunnsinnretninger. Oppfinnelsen vil her kunne bidra til en betydelig reduksjon i utstyrsbehov og volum, noe som kan være av avgjørende betydning på større havdyp. The invention will be particularly suitable for systems, with a need for an accumulator function, which are normally charged at one ambient pressure and then moved to another ambient pressure. Typical areas are temporary equipment for use on seabed installations. The invention will be able to contribute to a significant reduction in equipment requirements and volume, which can be of decisive importance at greater ocean depths.

Dagens metoder for å skaffe tilveie akkumulert energi i utstyr som skal utføre midlertidig arbeid på havbunnsinnretninger, er i stor grad basert på å forlade akkumulator på overflaten for å skaffe ett tilgjengelig trykkoverskudd i forhold til omgivelsen. Dette trykkoverskuddet reduseres betraktelig om akkumulatoren senkes ned til en vanndybde på f. eks 2000m, hvor trykkreduksjonen vil være på ca 200 bar. Reduksjonen i trykkoverskuddet kompenseres normalt ved å øke akkumulatorvolumet, noe som igjen blir uforholdsmessig utstyrs- og plass-krevende. Today's methods for providing accumulated energy in equipment that will perform temporary work on seabed installations are largely based on placing the accumulator on the surface to provide an available pressure surplus in relation to the environment. This excess pressure is reduced considerably if the accumulator is lowered to a water depth of, for example, 2000m, where the pressure reduction will be approximately 200 bar. The reduction in the excess pressure is normally compensated by increasing the accumulator volume, which in turn becomes disproportionately equipment- and space-demanding.

Fra kjent teknikk skal blant annet US, 4.777.800, US 6.418.970, US 6.202.753 og EP 0078031 trekkes frem. US, 4.777.800 omhandler en trykkakkumulator for bruk i forbindelse med undervannsutstyr, med tre delkamre adskilt av stempler, hvor et første kammer er innrettet til å innta samme trykk som omgivelsene, et andre kammer er utsatt for lavtrykksgass og et tredje kammer står i forbindelse med et fluid. From prior art, among others, US, 4,777,800, US 6,418,970, US 6,202,753 and EP 0078031 should be highlighted. US, 4,777,800 relates to a pressure accumulator for use in connection with underwater equipment, with three sub-chambers separated by pistons, where a first chamber is arranged to assume the same pressure as the surroundings, a second chamber is exposed to low-pressure gas and a third chamber is connected with a fluid.

En stor del av oppgavene til akkumulatoren når denne inngår i midlertidige systemer for arbeid på vann-, eller hydrokarbonførende havbunnsinnretninger, er å støtte nødsystemer som normalt ikke skal betjenes. Dette medfører at en stor del av akkumulatorens energi er beredskapsenergi, som ikke er planlagt brukt. A large part of the tasks of the accumulator when it is included in temporary systems for work on water- or hydrocarbon-bearing seabed facilities is to support emergency systems that should not normally be operated. This means that a large part of the accumulator's energy is standby energy, which is not planned to be used.

Foreliggende oppfinnelse har til formål å erstatte deler av et systems krav til en forladet akkumulator, ved å erstatte denne med en trykkgenereringsenhet som kan aktiveres ved behov, gjennom å kombinere eksisterende og ny teknologi med nye metoder og systemer. The purpose of the present invention is to replace parts of a system's requirements for a charged accumulator, by replacing this with a pressure generating unit that can be activated when needed, by combining existing and new technology with new methods and systems.

Trykkakkumulatoren i følge oppfinnelsen omfatter foretrukket en gassgenerator, fortrinnsvis en saktebrennende eksplosiv enhet, som er anbrakt i et trykkompensert kammer. Kammeret står i forbindelse med legemet eller væsken som skal utsettes for energi, ved hjelp av et stempel eller en membran. Oppfinnelsens hovedelement, gassgeneratoren, kan initieres ved hjelp av én, eller flere uavhengige, avfyrings detonatorer, med tilhørende systemer. The pressure accumulator according to the invention preferably comprises a gas generator, preferably a slow-burning explosive unit, which is placed in a pressure-compensated chamber. The chamber is connected to the body or liquid to be exposed to energy, by means of a piston or a membrane. The invention's main element, the gas generator, can be initiated by means of one or more independent firing detonators, with associated systems.

Det kan også være anrettet flere uavhengige gassgeneratorelementer, med tilhørende initieringssystemer innenfor rammene av samme trykkompenserte kammer for å oppnå ønsket effekt og/eller redundans. Several independent gas generator elements can also be arranged, with associated initiation systems within the framework of the same pressure-compensated chamber to achieve the desired effect and/or redundancy.

Trykkakkumulatoren i følge oppfinnelsen kan settes sammen i et hentbart magasin, for å representere både kraftbehov, redundans samt tilby muligheter for å hente et benyttet system fra magasinet, for så å erstatte dette med en ubrukt enhet, mens hovedsystemet som har kraftbehovet er i operasjon. For havbunnsinstallasjoner kan betjening av magasinet fortrinnsvis opereres av en ROV. Videre kan trykkammer og kompenseringskammer være utrustet med ventiler som muliggjør avblødning av innestengt trykk på en sikker måte når kammeret har vært benyttet, eller vært utsatt for høyere omgivelsestrykk enn ved sammenstilling. The pressure accumulator according to the invention can be assembled in a retrievable magazine, to represent both power demand, redundancy and offer opportunities to retrieve a used system from the magazine, in order to replace this with an unused unit, while the main system that has the power demand is in operation. For seabed installations, operation of the magazine can preferably be operated by an ROV. Furthermore, the pressure chamber and compensating chamber can be equipped with valves that enable bleeding of trapped pressure in a safe way when the chamber has been used, or has been exposed to higher ambient pressure than during assembly.

For å initiere gassgeneratoren via en detonaturfunksjon, kan det benyttes flere alternative systemer, eventuelt i kombinasjon, for å få dette utført. Både direkte-koblede systemer, så vel som akustiske- eller andre indirekte systemer kan benyttes. To initiate the gas generator via a detonation function, several alternative systems can be used, possibly in combination, to get this done. Both direct-coupled systems as well as acoustic or other indirect systems can be used.

Denne oppfinnelsen innbefatter trykkompensert kammer for gassgenerator, initieringsenhet, og stempel eller blære/membran for overføring av krefter. This invention includes pressure compensated chamber for gas generator, initiation unit, and piston or bladder/diaphragm for transmission of forces.

Oppfinnelsen tar ikke hensyn til hvordan kreftene som genereres overføres, opereres eller kjøres, og dekker som sådan enhver form for slike metoder. The invention does not consider how the forces generated are transmitted, operated or driven, and as such covers any form of such methods.

En foretrukket utførelse av en trykkakkumulator i følge oppfinnelsen er kjennetegnet ved karakteristikken i det selvstendige krav 1, mens foretrukne alternative utførelser er kjennetegnet ved de uselvstendige kravene 2-9. A preferred embodiment of a pressure accumulator according to the invention is characterized by the characteristic in the independent claim 1, while preferred alternative embodiments are characterized by the non-independent claims 2-9.

Et fortrukket anvendelsesområde er definert i det selvstendige krav 10, med tilhørende uselvstendig krav 11. A preferred application area is defined in the independent claim 10, with associated non-independent claim 11.

Foredeler med en trykkakkumulator i følge oppfinnelsen er at den kan være uten energi inntil initiert og at den kan initieres ved behov. Oppfinnelsen kan i Advantages of a pressure accumulator according to the invention are that it can be without energy until initiated and that it can be initiated when needed. The invention can i

prinsippet benyttes både på systemer/utstyr på land, offshore, i verdensrommet, så vel som på havbunnssystemer. Den kan monteres i hentbare magasiner som kobles (elektrisk og hydraulisk) f. eks på havbunnen ved hjelp av ROV. Den kan parallellkobles for å oppnå ønsket effekt og/eller redundans. Den kan monteres direkte på utstyr (f. eks ventilaktuator) som har kraftbehovet. Overflødig trykk the principle is used both on systems/equipment on land, offshore, in space, as well as on seabed systems. It can be mounted in removable magazines that are connected (electrically and hydraulically) e.g. on the seabed with the help of ROVs. It can be connected in parallel to achieve the desired effect and/or redundancy. It can be mounted directly on equipment (e.g. valve actuator) that has the power requirement. Excess pressure

Andre fordeler er at trykkakkumulatoren kan utrustes med alle avfyrings-mekanismer som er normalt tilgjengelige i markedet, eller med spesialdesignete løsninger. For eksempel kan den utrustet med en detonator/initiator som er av såkalt sikker type, dvs. at det bla. ikke er behov for radiotaushet eller andre systemnedstengninger, eller den kan utrustes med redundante initiator/- detonator systemer, helst av forskjellig fabrikat, eventuelt forskjellig produksjons "baten". Den kan initieres enten ved hjelp av direkte elektriske eller hydrauliske signaler, eller ved hjelp av indirekte avfyringsmetoder som akustikk og elektromagnetisme, og den kan utrustes med alle gassgeneratorer (slow burning powder charge) som er normalt tilgjengelige i markedet, eller med spesialdesignete løsninger. Other advantages are that the pressure accumulator can be equipped with all firing mechanisms that are normally available on the market, or with specially designed solutions. For example, it can be equipped with a detonator/initiator that is of the so-called safe type, i.e. that it e.g. there is no need for radio silence or other system shutdowns, or it can be equipped with redundant initiator/detonator systems, preferably of different make, possibly different production "baten". It can be initiated either by means of direct electrical or hydraulic signals, or by means of indirect firing methods such as acoustics and electromagnetism, and it can be equipped with all gas generators (slow burning powder charge) normally available on the market, or with specially designed solutions.

Gassekspansjonskammeret 14b er igjen separert fra trykkammeret 14c ved hjelp av trykkstempelet 18. Stemplene 16,18 representerer en bevegelig trykkbarriære mellom kamrene. Figure 1 shows a typical assembly of the invention when it is used to generate pressure against the pressure chamber 14c. As the figure shows, a gas generator 20 with associated initiator/detonator 22 is arranged between two pistons 16,18 inside the sleeve-shaped main body 12. The inner main chamber 14 is, as the figure shows, preferably divided into three chambers by means of the aforementioned pistons 16,18 . The compensation chamber 14a is separated from the gas expansion chamber 14b by means of a compensation piston 16. The gas expansion chamber 14b is again separated from the pressure chamber 14c by means of the pressure piston 18. The pistons 16,18 represent a movable pressure barrier between the chambers.

Det er videre fortrinnsvis anrettet ventiler 26,28 for å kunne blø av trykk fra kompenserings- og/eller gassekspansjonskammeret 14a hhv. 14b. I kompenseringskammeret 14a er det anrettet en tilbakeslagsventil 24 som forhindrer trykk fra kammeret i å slippe ut igjen. Trykkammeret 14c inneholder et medium i for av for eksempel væske eller gass, som skal tilføres trykk. Trykkammeret 14c omfatter ved en ende et utløp 30 som kobles til systemet som skal nyttegjøre seg av trykket. Til nevnte ende eller utløpsåpning kan det være anordnet en blære, membran eller lignende (ikke vist) for overføring av trykk til det eksterne utstyret. Valves 26, 28 are also preferably arranged to be able to bleed off pressure from the compensation and/or gas expansion chamber 14a or 14b. In the compensation chamber 14a, a non-return valve 24 is arranged which prevents pressure from the chamber from escaping again. The pressure chamber 14c contains a medium i for example liquid or gas, which is to be pressurized. The pressure chamber 14c comprises at one end an outlet 30 which is connected to the system which is to make use of the pressure. A bladder, membrane or the like (not shown) can be arranged at said end or outlet opening for transferring pressure to the external equipment.

Gassgeneratoren 20 i gassekspansjonskammeret 14b kan fortrinnsvis være en saktebrennende (deflagrerende) eksplosiv ladning (slow burning powder charge). Initiator 22 kan være av flere utforminger og prinsipper som er forenlig med aktuell gassgenerator og funksjonskrav (temperatur og avfyringssikkerhet spesielt). En elektrisk ledning 34 kan fortrinnsvis være ført inn til initiator/- detonator 22 fra utsiden via spesielle trykkmotstandsdyktige gjennomføringer med elektrisk leder i, for å kunne utløse initiator/detonator og derved gassgeneratoren. The gas generator 20 in the gas expansion chamber 14b can preferably be a slow burning (deflagrating) explosive charge (slow burning powder charge). Initiator 22 can be of several designs and principles that are compatible with the current gas generator and functional requirements (temperature and firing safety in particular). An electric line 34 can preferably be led into the initiator/detonator 22 from the outside via special pressure-resistant bushings with an electric conductor in it, in order to be able to trigger the initiator/detonator and thereby the gas generator.

Figur 2 viser en alternativ foretrukket utførelse som er bygget opp etter samme prinsipp som nevnt i forbindelse med figur 1, med det unntaket at trykket som blir generert i gassekspansjonskammeret 14c overføres direkte til en aksling 32 via trykkstempelet 18.1 denne konfigurasjonen er det anrettet en ventilerings-funksjon 36 i hylsen for at eventuell væske eller gass skal kunne evakuere uten Figure 2 shows an alternative preferred embodiment which is built up according to the same principle as mentioned in connection with Figure 1, with the exception that the pressure generated in the gas expansion chamber 14c is transferred directly to a shaft 32 via the pressure piston 18.1 in this configuration, a ventilation function 36 in the sleeve so that any liquid or gas can evacuate without it

å skape en mulig låsesituasjon. Det kan også her, dersom ønskelig, benyttes en blære, membran eller lignende for overføring av trykk til det eksterne utstyret. to create a possible lock situation. Here too, if desired, a bladder, membrane or similar can be used to transfer pressure to the external equipment.

Figur 3 viser en utførelse av foreliggende oppfinnelse som beskrevet under figur 1. Trykkakkumulatoren 10 er her klargjort under atmosfæriske omgivelser. Som det fremgår av skissen er nå kompensasjonskammeret 14a redusert til et mini-mum med et atmosfærisk trykk, og mottrykket i trykkammeret 14c er også til-svarende som det atmosfæriske trykket. Figur 4 viser en utførelse av foreliggende oppfinnelse som beskrevet under figur 3. Trykkakkumulatoren 10 er her eksempelvis senket ned til 2000 meters havdyp. Som det fremgår av skissen har nå kompensasjonskammeret 14a blitt tilført samme trykk som omgivelsen. Dette medfører at trykkakkumulatoren 10 oppnår full effekt av trykket som skal genereres i gassekspansjonskammeret 14c, uten å først måtte overkomme omgivelsestrykket. Figur 5 viser trykkakkumulatoren som beskrevet under figur 4, med den for-skjellen at gassgeneratoren 20 er initiert ved hjelp av initiator/detonator 22, og at trykkoppbyggingen har funnet sted. Trykkakkumulatoren 10 er nå trykksatt og representerer lagret, tilgjengelig energi. Figur 6 viser trykkakkumulatoren som beskrevet under figur 5, med den for-skjellen at det har vært et forbruk av energi fra trykkammeret 14c, som igjen medfører en posisjonsendring av trykkstempelet 18, og en reduksjon av gjen-værende energi i trykkammeret 14c. Figur 7 viser trykkakkumulatoren som beskrevet under figur 2, hvor gassgeneratoren 20 er initiert ved hjelp av initiator/detonator 22, og trykkoppbyggingen har funnet sted. Figur 8 viser trykkakkumulatoren som beskrevet under figur 7, hvor trykkoppbyggingen har påført trykkstempelet 18 og akslingen 32 en stor nok kraft til at denne har endret posisjon til en aktivisert tilstand. Figure 3 shows an embodiment of the present invention as described under Figure 1. The pressure accumulator 10 is here prepared under atmospheric surroundings. As can be seen from the sketch, the compensation chamber 14a is now reduced to a minimum of atmospheric pressure, and the back pressure in the pressure chamber 14c is also similar to the atmospheric pressure. Figure 4 shows an embodiment of the present invention as described under Figure 3. The pressure accumulator 10 is here, for example, lowered to 2000 meters sea depth. As can be seen from the sketch, the compensation chamber 14a has now been supplied with the same pressure as the surroundings. This means that the pressure accumulator 10 achieves the full effect of the pressure to be generated in the gas expansion chamber 14c, without first having to overcome the ambient pressure. Figure 5 shows the pressure accumulator as described under Figure 4, with the difference that the gas generator 20 is initiated by means of initiator/detonator 22, and that the pressure build-up has taken place. The pressure accumulator 10 is now pressurized and represents stored, available energy. Figure 6 shows the pressure accumulator as described under Figure 5, with the difference that there has been a consumption of energy from the pressure chamber 14c, which in turn entails a change in position of the pressure piston 18, and a reduction of remaining energy in the pressure chamber 14c. Figure 7 shows the pressure accumulator as described under Figure 2, where the gas generator 20 is initiated by means of initiator/detonator 22, and the pressure build-up has taken place. Figure 8 shows the pressure accumulator as described under Figure 7, where the pressure build-up has applied a force large enough to the pressure piston 18 and the shaft 32 that it has changed position to an activated state.
